special lead forming, add type number as suffix to part number.
(12) Initial on-state current = 400 mA dc for 16 A to 40 A devices and
100 mA for 6 A to 12 A devices.

Gate Characteristics
Teccor triacs may be turned on in the following ways:
In-phase signals (with standard AC line) using Quadrants I
and III
Application of unipolar pulses (gate always negative), using
Quadrants II and III with negative gate pulses
In all cases, if maximum surge capability is required, gate pulses
should be a minimum of one magnitude above minimum I
GT
rating
with a steep rising waveform (
≤
1 μs rise time).
If QIV and QI operation is required (gate always positive), see
Figure AN1002.8, “Amplified Gate” Thyristor Circuit.
Definition of Quadrants
Electrical Isolation
Teccor’s isolated alternistor packages withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab, over
the operating temperature range of the device. The following iso-
lation table shows standard and optional isolation ratings.
* UL Recognized File E71639
** For 4000 V isolation, use V suffix in part number.
* UL Recognized Product per UL File E71639
** For 4000 V isolation, use V suffix in part number.
